Tyra Banks welcomes first child -- a baby boy -- via surrogate

Tyra Banks has something new to smize about: The supermodel-turned-businesswoman is now a mom -- and not just to a house full of prospective models.

The "America's Next Top Model" maven and boyfriend Erik Asla welcomed son York Banks Asla via surrogate, she announced late Wednesday on Instagram. The fierce 42-year-old posted a simple photo of a baby cap on the photo-sharing site to reveal her first-time mom status.

"The best present we worked and prayed so hard for is finally here," Banks wrote.

"He's got my fingers and big eyes and his daddy Erik's mouth and chin. As we thank the angel of a woman that carried our miracle baby boy for us, we pray for everyone who struggles to reach this joyous milestone. York Banks Asla, welcome to the world."

"When I turned 40, the one thing I was not happy about is that I did not have kids," she told the mag last September. "When you're like, 'OK, I'm just going to do it,' then it's not so easy as you get older."
